In all the world’s great herbal traditions, the use of single herbs (simples) is virtually unknown. Complex formulas are most often used and are, if properly formulated significantly more effective than individual remedies.  With classic traditional formulas there are clear strategies to create a mixture that is more than the sum of its parts (1 + 1 = 3, 4 or 5).  There are multiple ways to create synergy and avoid antagonism (1 + 1 = 1).  In this class we will look at the concepts and techniques used in TCM, Ayurveda, Unani-tibb, Physiomedicalism, Eclectic Medicine, Siddha and Western herbal practice that allow the clinician to achieve superior results and repeated clinical success.
